This invention relates "to paint stirrers,

and more particularly to devices of this'cha'racter adapted for manualoperation to give a final stirring to ready-prepared paint just beforethe, application thereoff'to theisurface to-be painte A substantial partbf the' 'market'forlpaint have little or or home userswill buya can. ofpaint 'from the local store, P color chart, and I then before", applymgthe paint merely stir it a few times with a" stick or other home-madeimplement." As aresult, an'inferiorefl'ect is produced when v the poorlymixed paint is applied to the surface, as it will not be of uniformconsistency,

causing a mottled surface which will cgenerally vary considerably incolor from that of the color chart. Upon complaintTto'the vendor thatthe paint did not correspond to the color chart, an experienced painteris often sent out by the store'who will properly mix the paint andproduce a paint surface which exactly coincides with the colorichart,"proving that the entire difficulty ism the final stirring of the paint.I, 7 In order to "cope with this problem =1t 1s proposed toprovide asimple;paint stirrer which may be used'by aninexperienced painter, whichwill thoroughly mix thepaint so that the desired efiect may be produced.By economical manufacture, these stirrers may be supplied gratis by thevendor with each can of paint. 7

The present invention has'to do with this problem and has for itsgeneral-object-to simplify andimprove the construction-an operation ofdevices of -this character,

A specific object of the invention is toprovide a paint stirrer whichwill thoroughly stir the paint at the bottom of the can and permit thepaint thrown up Ifromithe bottom to "overflow the stirrer at the topwithout "spilling out of the can. 7 r

Y 1 Referring more particularly to'the drawings, thep'aint stirrercomprises, essentially,

a handle-10 and a, blade .11; The handle 10 comprises a vertical shaft,thefilower "portion of which is substantially straight. The

upper" oportion offthe shaft 10 is bent laterally'as at 10,fthenvertically upward as at "12, again laterally as atfllS, and finally ver-F:

The blade 11 perforated by a plurality of apertures 18 which arepreferably-distrib uted along the bottom and side margins of the blade.These apertures facilitate the mixing of the paint inan obvious manner.The blade is rigidly secured to the shaft 10 by any desired means,whichin the embodiment shown comprises rivets '19.

preferred shown in Figs. 1 and 2 a second blade '20 is p asses throug.Zontal plane but at of each blade are .plate 11 reversed .may bepunched alike,

7 The above description applies equally to each of the figures of thedrawings, but in the embodiment of the invention provided on the otherside'of the shaft 10, the shaft holding the blades in spaced relation.The blade 20 is preferably parallel to and similarto the blade 11 withthe excep-- tion that it is provided with apertures 21 which areapertures 18 in the blade 11, but preferably in overlapping relationtherewith. This arrangement provides that each of the bladeswillpresent' a different surface, of revolution and thus effect a morethorough stirring or cutting of the paint, as the paint which htheapertures 18 cannotpass undisturbed through apertures 21.

While the disalignment of the apertures 18 and 21 may be provided invarious ways, it will be noted that in the specificembodiment, thecorresponding holes are in the-same horidifierent distances from Hencethe holes are at different distances from theadj'acent side edges, beingoifset in the direction of the centrifugal force set up by the stirring.

It will be noted that theholes of one side respectively spaced asdistances from the shaft 10 and the side edge, which are different fromthe corresponding distances of the opposite holes in the other side. Aneconomy of manufacture islprovided thereby as the plate 20 may be merelya Thus all plates ll and 20 and the disalignment taken care ofduringassembly by merely rethe axis of rotation.

Thus, in mixing, it is quite import ant thatvthe surface of revolutioncover substantially the entire bottom of thecan. Agiedges. from. thecorresponding upper portion of the can. The tapered sides of the blade'11, or the blades 11 and 20, will permit the paint thrown up from thebottom of the can to overflow the blades in passing, and such overflowwill cause an additional agitation of the paint.

It will] be obvious that the specific structure shown and described issusceptible of very many modifications within the scope of the broaderidea thereof. It is, therefore, to. be understood thatthe scope of theinvention is not to be limited to the details shown and described butincludes such embodiments of the broad idea as fall within the scope ofthe sub-joined claims.

Having thus described the invention what I claim as new and desire tosecure as Letters Patent of theUnited States is: i

, 1. A, paint stirrer comprising a vertical shaft,- nd bladessecuredadjacent their intermediate portions toeach side ofjthe lowerportion of said shaftand spaced apart thereby, there, being a singleintegral perforated blade oneach side of said shaft.

2. A paint stirrer comprising a vertical jacent their intermediateportions to the 0p- .posite sides of the lower portion of said shaft,each of said blades being providedwitha plurality of apertures, on eachside of said blade being out of 3. A paint stirrer comprising a verticalshaft, blades secured to the lower portion of said shaft, each of saidblades being provided with. a, plurality of apertures, the apertures, ofone blade being out of alignment with the apertures of the other but inoverlappingrelation therewith. I Y I 4. A paint stirrer adapted to stirpaint in a can, c0mprising ajblade' having a lower edge adapted toconform to the bottom of a paint can and extend toward the sidesthereof, and

having side edges extending upwardly from said lower edge and inwardlyfrom the sides:

of: the can. topermit the paint thrown up from the bottom, of the can tooverflow the upper portion of the blade, without spilling out, of-thecan, said blade havin-gapertures spaced from one side edge, and otherapertures spaced; different distances from the other side edge.

5. A paint stirrer comprising a vertical shaft and a plurality ofparallel blades connected thereto, each of said blades beingperforated-in. the-same pattern, the perforations of one blade being atdifferent distances from the shaft from the perforations of anotherblade. i 1

6. A paint stirrer having a'blade'adapted to rotate about a verticalaxis, and provided with holes in each side, the holes in one side beingat different distances from the side holes of the Q other side and anidentical blade reversed with respect to-the first mentioned blade.

7. ,A paint stirrer having a plurality of 7 blades adapted to rotateabout a vertical axis,

. and each provided with a plurality of eccentric apertures, one of saidblades being re versed, whereby the apertures therein are disposed atdifferent distances from the axis of rotation from the correspondingapertures of the other.

8. A paint'stirrer adapted to stir paint in a receptacle, comprising ablade rotatable about a vertical axis, and having a straight lower edgeadapted to contact with the bottom of the receptacle for substantiallythe full diameter thereof to dislodge paint therefrom, said bladeshaving a plurality of eccentric a'per tures, the upper edges of saidblade converg- I ing thereabove, whereby rotation of the blade.

causes the paint dislodged by said lower edge to swirl over saidconverging upper edges and cooperate with the orificeeffect of saidapertures to cause rapid'mixing of the paint. 7
